Application nee February 25, 1922. Serial no. 589,248.

To all whom it may concern:

Be it known that I, ALBERT a citizen of the United States, residing at St. Joseph, in the county of Buchanan and State of Missouri, have invented certain new and useful i-Improvements in Refrigerator Display Counters, of which the following is aspecification.

This invention relates to refrigerators and more particularly to displa counters.

tank again at the opposite end thereof forrecooling.

A further object is to arrange an overflow trough in the lower part of the cooling chamber whereby the overflow of the brine (when using ice) is utilized as an additional cooling means.

A further object of the invention is to so arrange the several parts that they are readily accessible for repair, the cooling tank and shelves being so arranged that the former may be readily refilled and the latter with its contents may be easily reached from the rear of the counter.

Figure 1 is a perspective view.

Fig. 2 is a rear view.

Fig. 3 is a transverse section of Fig. 1.

Fig. 4 is an end elevation.

\ Fig. 5 is a longitudinal section of Fig. 3.

Fig. 6 is a modified View showing the cool ing coils in the brine tanks as a substitute for ice as a cooling medium.

The refrigerator is provided with the usual insulating walls, and comprises a double chamber 1 and a lower non-cooled storage compartment 2, it being understood howeverthat the lower compartment may be entirely open and the motor and circulating pump placed on the floor. The numeral 3 indicates. the bottom of the upper c mber and 4 the vertical front wall thereof, the bottom slanting upwardly as at 5 toward the inner vertical portion 4 of the front wall,

causing the air being circulated within the H. Eamon,

chamber tOJShOOt upwardly. A front transparent wall 6 consisting of a plurality of thicknesses of glass and having an inner surface 6 extends upwardly from the wall 4, at, the upper end of the inner vertical portion 4' and slants inwardly toward the rear of the case, terminating in a. top horizontal portion 7. The rear wall 8 of the display chamber is preferablv solid and has projecting inwardly therefrom a horizontal counter 9. Extendlng upwardly diagonally from the counter portion 9 and adapted to engage the rear end of the top portion 7 is the'rear upper wall 10 of the display compartment, preferably being provided with a'plurality of doors 11. These doors llare preferably hinged at their lower edge as at 12, being provided at their upper edge with suitable latches 13, the object being to have the upper end thereof swing outwardlyv and inwardly in order to increase the circulation of air in the chamber as the door being closed would have atendency'to push the air from the upper-portion through the bottom of the chamber. The counter portion 9 is likewise provided with hinged doors 14, whereby the ice receptacle hereinafterdescribed may be easily filled.

Directly beneath the rear counter portion 9 is arranged an ice receptacle 15.'- This receptacle preferably consists of a inetaltanksupported upon suitable legs 16. This tank extends approximately the full length of the case. The front wall of the tank is preferably provided with a plurality of V- shaped recesses 17 adapted. to increase the cooling area of the tank. Arranged in the lower portion ofthe tank a wire ice rack- 18. In this form'of cooling tank it is preferable to use cracked ice, which is salted so as to force it to melt faster and absorb more heat, .the brine therefrom collecting in the bottom of the tank.

Arranged in the display compartment is a cooling coil 20 consisting of a series .of 1

length of pipes. As disclosed inFig. 3 a pipe 21 leading from the bottom of the tank is connected by a coupling 22 to a length of pipe 23 toa force pump 24 arranged in the lower non-cooled compartment. Leading therefrom is a pipe 25 extending vertically and provided on its upper end with a shaped connection 26 arranged above the level of the coil and connected thereto by a pipe 27. -The opposite end of the coil likewise is connectedto the lower part of the from t e coil, being provided with a shaped connection 29, the latter being connected by a coupling to a pi e 31 leading to the lower sideof the tank. alves 3233 arranged at opposite ends of the tank permit the circulation being cut off .entirely, and

the U-shaped connections serve to hold the liquid in the coils when the pump is momentarily stopped. An electric motor 34 1s arranged in the low r compartment and is suitably connected to the pump 27 as by means ofa belt 35 serving to drive the pump. A switch 35" may beplaced at any convenient place outside of the case for controlling the motor. g

Arranged below the cooling coil is a drip pan 36 extending full length of the compartment, and divided longitudmally by a partition 37. Leading from the cooling tank at approximately the same level as the ice supporting rack is an over flow pipe 38, this pipe in turn leading to the drip pan, whereby the liquid upon leaving the tank flows the complete length of the compartment, finally discharging to the outlet 39.

Arranged above the cooling coils and adjacent the inner vertical portion 4 is a latticed or reticulated metal shelf 40, being supported by suitable cross strips 41erranged transversely of the coil.' An L- shaped metal strip of angle-iron 42 extends longitudinally of the strips serving to keep the cross strips properly spaced and holding the shelf in place. At the rear of the metal shelf 40 is a vertically arranged latticed metal guard or reticulated element 43, being suspended from the upper portion of the cooling compartment by suitable hooks 44. As shown the cooling compartment is provided at each end with doors -45 wherev by the shelf 40 and the guard 43 maybe readily removed from either end of the case for cleaning.

Fig. 6 is amodified view showing a coil 46 in the cooling tank 15 whereby the contents thereof may be cooled by artificial means. When using the coil as a cooling means the over flow pipe 38 is turned to a vertical position as the quantity of brine or other cooling medium in the tank and coolwardly and rearwardly extending window portion connected at thetopof said vertical portion, and a rearwardly..and downwardly slopin 'fioor connected to the lower portion of sai vertical portion, a shelf adjacent the vertical portion forfi viding the chamber memes ing chamber extending between the $10 ing floor and said shelf, whereby an a equate and efiicient circulation of air is permitted in both the cooling and display compartments.

2. In, a refrigerating display counter, a cooling display chamber, the inner front surface of said cooling display chamber having a substantially vertical portion, an upwardly and rearwardly extendin window portion connected at the top of said vertical portion, and a rearwa dly and downwardly sloping floor connected to the lower portion of said vertical portion, a shelf adjacent the vertical portion for dividing the chamber into an upper display compartment and a lower cooling compartment, and a circulatmg system in the upper part of saidcooling chamber above the sloping floor, whereby an adequate and efficient circulation of air is permitted in both the cooling and display compartments, an ice compartment in the rear of said refrigerator, a receptacle in said ice compartment, a shelf dividing the receptacle into an upper ice compartment and a lower liquid compartment, said circulating system in series with the lower liquid compartmentof the receptacle, and an overflow pipe connected to the receptacle at substantially the level of the tray for normally maintaining a constant level of liquid in said receptacle.

3. A cabinet comprising a display chamber, an ice container arranged at the rear of said chamber, cooling coils arranged in the lower part of said cooling chamber, each end thereof being connected to said ice container, a circulating means arranged in series with said cooling coils, a reticulated shelf arranged above said cooling coil and supported upon a longitudinally extending an gle-iron, and a vertical reticulated element suspended from said chamber and impinging against, and supported by, said angle-iron. 4. A refrigerator comprising a display chamber, an ice container arranged at the rear of said chamber, cooling coils arranged in the forward part of said cooling chamber, each end thereof being connected to said ice container, a circulating means arranged in series with said cooling coils, means in the circuit to stop syphonic action if the circulation is stopped, and a latticed shelf arranged above said cooling coils, doors arranged in the upper part of said cooling chamber for access to the shelf, and doors arranged above the ice container for refilling the same. i In testimony whereof I affix my signature.
